"Kwiintlobo zentamo ze-femoral ezingezizo ezikhulu, indlela yokubopha yangaphakathi esetyenziswa kakhulu yi-'inverted triangle' configuration enezikrufu ezintathu. Izikrufu ezibini zibekwe kufutshane nee-cortices zangaphambili nangasemva zentamo ye-femoral, kwaye esinye isikrufu sibekwe ngezantsi. Kwi-anteroposterior view, izikrufu ezibini ezikufutshane ziyadibana, zenza ipateni 'yezikrufu ezibini', ngelixa kwi-lateral view, kubonwa ipateni 'yezikrufu ezi-3'. Olu lungiselelo luthathwa njengolona ndawo ifanelekileyo yezikrufu."
"I-medial circumflex femoral artery yeyona nto iphambili enika igazi entlokweni ye-femoral. Xa izikrufu zibekwe 'ngaphakathi-ngaphandle-ngaphakathi' ngaphezulu kwecala elingasemva lentamo ye-femoral, oko kubeka umngcipheko wokwenzakala kwemithambo yegazi, okunokubeka emngciphekweni ukunikezelwa kwegazi entanyeni ye-femoral kwaye, ngenxa yoko, kuchaphazele ukuphiliswa kwamathambo."
"Ukuthintela ukwenzeka kwento ethi 'in-out-in' (IOI), apho izikrufu zidlula kwi-cortex yangaphandle yentamo ye-femoral, ziphume kwithambo le-cortical, zize ziphinde zingene kwintamo ye-femoral kunye nentloko, iingcali zasekhaya nakwamanye amazwe zisebenzise iindlela ezahlukeneyo zokuvavanya ezincedisayo. I-acetabulum, ekwicala langaphandle lentamo ye-femoral, kukuxinana kwethambo. Ngokufunda ubudlelwane phakathi kwezikrufu ezibekwe ngaphezulu kwecala langasemva lentamo ye-femoral kunye ne-acetabulum kumbono we-anteroposterior, umntu unokuqikelela okanye ahlole umngcipheko we-screw IOI."
▲ Lo mzobo ubonisa umfanekiso wethambo le-cortical le-acetabulum kumbono we-anteroposterior we-hip joint.
Olu phononongo lubandakanye izigulana ezili-104, kwaye kwahlolwa ubudlelwane phakathi kwethambo le-cortical le-acetabulum kunye nezikrufu zangasemva. Oku kwenziwe ngokuthelekisa ii-X-rays kwaye kwancediswa yi-postoperative CT reconstruction ukuvavanya ubudlelwane phakathi kwezi zimbini. Phakathi kwezigulana ezili-104, ezili-15 zibonise into ecacileyo ye-IOI kwii-X-rays, ezi-6 zazinedatha engaphelelanga yemifanekiso, kwaye ezili-10 zazinezikrufu ezibekwe kufutshane kakhulu nombindi wentamo ye-femoral, nto leyo eyenza uvavanyo lungasebenzi. Ke ngoko, amatyala angama-73 asebenzayo afakiwe kuhlalutyo.
Kwiimeko ezingama-73 ezihlalutyiweyo, kwi-X-reyi, iimeko ezingama-42 zazinezikrufu ezibekwe ngaphezulu kwethambo le-cortical le-acetabulum, ngelixa iimeko ezingama-31 zazinezikrufu ezingaphantsi. Ukuqinisekiswa kwe-CT kutyhile ukuba isenzeko se-IOI senzeke kwi-59% yamatyala. Uhlalutyo lwedatha lubonisa ukuba kwi-X-reyi, izikrufu ezibekwe ngaphezulu kwethambo le-cortical le-acetabulum zazinovakalelo lwe-90% kunye nokucaciswa kwe-88% ekuqikeleleni isenzeko se-IOI.
▲ Ityala Lokuqala: I-X-ray ye-hip joint kwi-anteroposterior view ibonisa izikrufu ezibekwe ngaphezulu kwethambo le-cortical le-acetabulum. I-CT coronal kunye ne-transverse views ziqinisekisa ubukho be-IOI phenomenon.
▲Ityala lesiBini: I-X-ray ye-hip joint kwi-anteroposterior view ibonisa izikrufu ezibekwe ngaphantsi kwethambo le-cortical le-acetabulum. Ii-CT coronal kunye ne-transverse views ziqinisekisa ukuba izikrufu ezingasemva zingaphakathi kwe-bone cortex ngokupheleleyo.
